Quake Watch 2013

What kind of fault is involved at that point . . . strike slip or what?

everything except Spreading Ridge Faults are there!, the main ones are to the east the Hikurangi Subduction zone, then across Cook Strait SW to NE is strike slip. The Cook Strait area is best described as the twist point of NZ, where the Tectonic Plates reverse overlap.

DOODNESS!

Sounds like it would be rough to predict what the area would look like say 10,000 or more years from now???

I was wondering if there was any predictable trend toward land rising between the two islands and joining them. Just an idle curiosity. LOL.

It was a bit hard for me to tell exactly where in the strait that those deeper quakes were . . . and then trending up to the rest of the quake levels. Maybe I need to just look more closely at the depth markers at USGS. I'm assuming that . . . 'dip stick' line of deeper quakes might be a subduction zone???

But then, if subduction is not really what's going on there . . . what might be?

THX THX.

There is a large earthquake coming in from the south....brb. Mexico Mag 6.86.5 (due to the usual USGS downgrade)

In the southern Gulf of California. map source

Wow, that one shook YMR pretty good...

more than one??????

It was large and very shallow. Depth is listed as only 1 km 8 km (revised a 2nd time). Good thing it was located in the sea, and not under a town.

I haven't seen any aftershocks yet.

@BobAtHome

Just one from all of the waveforms I've looked at. Here it is registered in Tucson, Arizona.

so techniclly, 2 events,,,6.8 & 6.5 ,,in short duration,,

would indicate?????,,any gps measurements yet?,,or beloved infra red,, sighhhh,, i wish,,how about infrared in 3d like ,,nevermind,,,

no Islands popping up anywhere?? lol

earthquake-report.com...

Update 18.37 UTC: The low populated coastal areas and the distance between epicenter and shore will reduce the impact of this quake. The quake happened shortly before 12.00 local time, when most of the people were at work. Local radio reports that some people left their workplaces after the earthquake, but the situation was relatively calm as the quake lasted only for a few seconds.
A very strong earthquake with M 6.5 occurred in Gulf of California, approx. 70 km off the coast of Sonora, Mexico. NO Tsunami warning was issued.
The ShakeMap of USGS shows a shaking with moderate intensity in Etchoropo and other areas of Sonora and Sinaloa. This could cause minor damage like cracked walls. 172.000 people should have felt the moderate shaking, according to USGS PAGER.

from people the common theme seems to be "First it was more like a fluid movement,not shake.",,,so taking them at there word,,a fluid movement,,,so back too the volcanic,, nature of the event,,being shallow,,do we have a new subterranian, vent?

have to be at least another 3+ all seismo reacted

@muzzy; @Puterman @anyone else who cares to chime in on such queries as a thought experiment . . .

THAT IS very fascinating.

What are your speculations about

1. the location of that deep quake and its implications

2. the location and geology of that deep quake in terms of the others in the broader region the last several months . . . i.e. what dynamic connections might there logically be?

3. Do you think that the river circling that local region is a function of an uplift at just the right pace for the river to take that path?

4. I haven't checked. How high are those mountains? Seems like a LOT of mass on top of the deep quake(s).

5. Let's pretend that . . . referencing the Banda Acheh quake and the undersea cliff that occurred rather instantly---IIRC--of several hundred feet high--IF such occurred in that fault system . . . where do you speculate it might occur and which side would rise vs which side staying the same or sinking?

6. Gads . . . such movements would likely mean a LOT of water splashing around rather destructively too, I'd guess.

7. And I doubt the North Island volcanoes would be resting peacefully with such movements going on???

May such never happen. However, looking at the 3D views of Japan and the 3D views of that NZ area . . . I'm not . . . say . . . overly comforted.


Not sure why NZ is so fascinating to me. It just is. So much interesting natural history and geology, for two.

One thing that cropped up while I was doing that was the location of that 348km deep quake, it is directly under the Marshall Range, which is unique in that it is part of what I call the NZ "geological button", check it out on Google Earth or Google Maps (terrain), -41.10, 172.43
almost a perfect circle around the mountains created by the river

edit on 10u29029013 by muzzy because: (no reason given)

I *think* this includes the Philippine large quake area:

I have just 1,000 quakes selected

Greetings! I am the creator of the IEB Google map and the 3DV viewer.

I always crave input on how to make it more user friendly.

You do *not* need to use the Twitter or other social button to share the URL.
Simply copy and paste the URL (or just drag it on a Mac) and you are done.

You see, the URLs (both in IEB and in 3DV) are updated each and every time you pan, zoom, or change search criteria. The advantage to using the Twitter route is that you are sharing a shortened URL, instead of the monstrously long default ones, but the long ones have advantages as in they contain all the parameters regarding lats, lons, mins and maxs, sort order and so forth.

I will have more to say but must get off to my mum's I'm LATE and you know how mothers are.

Yeah its an interesting area geologically. I had no idea how interesting until one day I was working on a new house being built at Eastbourne at the eastern side of Port Nicholson harbour and the hillside had been cut out to fit the house in, within the rock face you could see lines of layers with sea shells in them, but the layers were at 45 degrees to horizontal, and that was at 20-30 metres up from the sea. Can you imagine the force it would have taken to lift that mass of land up 45 degrees out of the sea, just mind boggling. Something really bad happened here in the distant past !.

no idea what that mountainous button or plug over in Kuhurangi National park might be caused by. Maybe it is holding back the entire magma content of the whole planet.
Probably nothing to it, just a surface feature, its about 1298m high at the quake location.

YEA! YEA! YEA!

CONGRATS ON YOUR WONDERFUL WORK.

The 3D viewer is fantastic.

I'm gleeful over using it.

I'm not sure how to get the actual images into ATS easily. Should, imho, be a 1-3 click process at best.

I have finally learned how to select a rectangle. Yea.

I wonder if there would be a way, once a user defined a rectangle and a 3D view of it--for such when a major foci of interest to be put into a pending bin for review for addition to your listed regions in the listed regions section you have in the sliding menu on the right.

Also, IIRC, it seems like, I have to reset the number of selected quakes each time. Seems to me there should be a way for that to be set once per browsing session.

Will make a note of your user name on ATS if I have any other ideas to share.

Oh, here's one . . . to have an option for the software search and compare any other reasonably defined similar regions with the one just examined. e.g.

What would be the similarities between NZ strait series of quakes and the Japanese series. My layman's view is that both have very deep quakes and a range of quakes up to shallower ones. How many regions are like that? etc.

I was going to ask for a slot to put lat & long into but the shift key and drag option is far easier. THX THX.


THANKS ENORMOUSLY FOR YOUR WONDERFUL PRODUCT AND WORK.

GREAT MUZZY. THX THX.

Will go play with your links.

Yeah, 45 degrees would take a lot of oooomph!

So . . . if there's a big shaking, that hillside will engulf the house nestled in it? LOL.
